Abstract
The invention relates to a button switch which comprises a shell, a foundation support, two buttons, a sliding block, a moving contact and a fixed contact. The two buttons are arranged on the shell, the moving contact and the fixed contact are arranged in the foundation support, and the shell covers the foundation support; the moving contact is in an arc shape, the top end of the moving contact is provided with a moving contact point corresponding to the fixed contact, the two sides of the middle of the moving contact protrude outwards to form side plates, the foundation support is internally provided with a moving contact support, the two side plates, corresponding to the moving contact, at one end of the moving contact support form two side plate grooves, and the centers of the bottoms of the side plate grooves protrude upwards; the moving contact is connected to the moving contact support through limiting cooperation between the side plates and the side plate grooves, and the sliding block abuts against the arc-shaped moving contact to slidably control swinging of the moving contact. According to the button switch, the contact points between the moving contact and the fixed contact is less, the cost of the contact points is saved, resistance caused by contact of multiple contact points is reduced, and the breaking speed is high.
Description
Technical field
The present invention relates to a kind of switch, especially a kind of push-button switch for cleaning machine.
Background technology
Push-button switch is the switch being realized switch on and off by pressing button, generally include two fixed contacts and a moving contact be connected with button, moving contact is connected across between two fixed contacts, moves up and down by button control moving contact the break-make realizing switch.This push-button switch, owing to there being two contact, causes the resistance of switch large, and can produce electric arc between contact when switch disconnects and easily burn out contact, and multiconductor improves the failure rate of push-button switch, reduces useful life.
Summary of the invention
For above-mentioned reasons, the object of the present invention is to provide a kind of structure simple, the push-button switch that contact is few.
For achieving the above object, the present invention adopts a kind of push-button switch, comprise shell, pedestal, button, slide block, moving contact, fixed contact, two buttons are arranged on shell, moving contact and fixed contact are arranged in pedestal, casing cover is on pedestal, slide block is arranged on the moving contact in pedestal, two buttons are connected with slide block two ends respectively, described moving contact is arc, the corresponding fixed contact in moving contact top arranges moving contact, in the middle part of moving contact, both sides outwardly convex forms side plate, moving contact rack is provided with in pedestal, two side plates of the corresponding moving contact in moving contact rack one end form two side plate grooves, the bottom centre of side plate groove upwardly, moving contact is connected on moving contact rack by side plate and the spacing of side plate groove, the swing of sliding control moving contact on the moving contact that slide block withstands on arc.
The present invention is set to described its center further and is hinged on shell, slide block lower end arranges pellet, pellet withstands on moving contact, slide block both sides form joint face upward, two joint faces are formed the connecting hole of cambered surface depression, two buttons extend to form button connecting rod in shell, and button connecting rod withstands in the connecting hole of slide block.Slide block is hinged on shell and controls vacillating now to the left, now to the right of slide block, compact conformation by two buttons, easy to assembly.
Two downward-sloping inclined-planes are formed respectively from prominence, center to both sides on the bottom that the present invention is set to described side plate groove further.Can fit when moving contact is rocked to the end and play a supporting role in inclined-plane, prevent moving contact to be out of shape.
The present invention is set to described its center further and forms jointed shaft, and the two ends first half of jointed shaft is inclined-plane, and shell forms hinge hole, and jointed shaft snaps in hinge hole hinged by inclined-plane.Inclined-plane on jointed shaft snaps in the easy to assembly of hinge hole.
The tail end downward bending that the present invention is set to described moving contact further forms barrier sheet.Barrier sheet can withstand on moving contact rack when moving contact disconnects, and prevents moving contact transition from swinging and being out of shape.
The sidewall lower semisection that the present invention is set to described side plate groove is further the inclined-plane inwardly shunk.Inclined-plane can facilitate the side plate of moving contact to be installed in side plate groove.
The invention has the beneficial effects as follows the moving contact adopting arc, moving contact is allowed to wave by button control slide block is mobile above moving contact, thus make the moving contact on moving contact top have certain stroke realization and the disconnection or closed of fixed contact, contact between this moving contact and fixed contact is few, save the cost of contact, reduce the resistance because of multiple contact, and breaking speed is fast.
